24 Removal Procedure
8. Indoor Heat Exchanger
Warning
Be sure to wait for 10 minutes or more after turning off all power supplies before
disassembling work.
In pump-down work, be sure to stop the compressor before disconnecting the
refrigerant pipe. If the refrigerant pipe is disconnected with the compressor operating
and the stop valve open, air may be sucked in and may generate an over-pressure in
refrigeration cycle, thus resulting in pipe rupture or accidental injury.
When removing or reinstalling the indoor heat exchanger, be sure to wear gloves or
wrap the indoor heat exchanger with cloths. (You may be injured by the fins.)
Caution
Be sure to conduct pump down operation before disassembling the refrigerant pipe.
If the refrigerant leaks, repair the spot of leaking, then collect all refrigerant from the
unit. After conducting vacuum drying, recharge proper amount of refrigerant.
From the viewpoint of global environmental protection, make sure to use a vacuum
pump for air purging.
